5 Materials

Roof safety hooks and their fastening systems shall be of metal and be resistant to corrosion as well as to

atmospheric and climatic influences. The material shall be free from faults and inclusions which may impair

their performance abilities.

The corrosion resistance shall be at least equivalent to that of hot-galvanized steel with a protective layer of

50 µm as in EN ISO 1461.

Parts of the fastening system beneath the roof covering may be from timber and shall then be protected

against atmospheric and climatic influences.
6 Dimensions and construction requirements
6.1 General

Roof safety hooks are installations for creating higher workplaces by securing a slater's ladder or by attaching

working platforms. They can simultaneously be used as anchorage points for personal protective equipment

against fall or for restraint.

The type and size of the fastening system shall be specified by the manufacturer.

6.2 Roof safety hooks
Roof safety hooks are differentiated as follows (see Figure 1):

 Type A: Roof safety hooks designed to accept tensile forces in the direction of the slope of the roof (y-

axis).

 Type B: Roof safety hooks designed to accept tensile forces in the direction of the slope of the roof (y-

axis), in the opposite direction (y-axis) as well as in the perpendicular direction and parallel to the roof

surface (x-axis).

Roof safety hooks shall have an opening of not less than 80 mm and not more than 150 mm, see Figure 2.

The height h of the hook shall be at least 120 mm.

A closed loop with an opening of at least 20 mm × 40 mm, e.g. a closed eyelet welded on (see Figure 2), to

which personal protective equipment against falls or for restraint may be attached, shall be fitted to the hook

base.

Where roof safety hooks are fastened by nails to the load-bearing roof construction, at least three radially

grooved nails (6,0 mm x 80 mm or 5,0 mm x 70 mm) shall be used.

The load-bearing capacity of all fastener systems shall be proved by testing according to Clause 7.

7 Requirements
7.1 Static load in the hook base

Roof safety hooks including their fastenings shall be designed for a single load of F ≥ 1,5 kN in the direction

of the y-axis in the hook base, see Figure 2.

Compliance with the requirements shall either be proved by means of a static calculation or, if this is not

possible, the product shall be tested according to 8.1.2.
NOTE For further calculations see ENV 1993 and ENV 1999.
---------------------- Page: 7 ----------------------
EN 517:2006 (E)

Under this load the distortion shall not be more than 5 mm in the direction of the y-axis.

The deflections and deviations shall be measured relative to the load-bearing roof construction.

7.2 Static load in the anchorage point

Roof safety hooks of Type A including their fastenings shall be designed to accept a single static load at the

anchorage point of F = 10 kN in the direction of the y-axis.

Roof safety hooks of Type B including their fastenings shall be designed to accept a single static load at the

anchorage point of F = 10 kN in the direction of the y-axis (both directions) as well as a single static load of

F = 10 kN in the direction of the x-axis.

Compliance with the requirements shall either be proved by means of a static calculation or, if this is not

possible, the product shall be tested according to 8.1.3.
The indicated single loads are test loads which shall at least be specified.
NOTE For further calculations see ENV 1993 and ENV 1999.

The roof safety hooks and their fastenings shall not fail under the single loads as indicated, the single loads

shall be held safely.
7.3 Fatigue strength

Roof safety hooks including their fastenings shall be designed to withstand the dynamic load of the test

according to 8.2 at any point where it is possible to attach personal protective equipment against fall or for

restraint (anchorage point).
7.4 Reaction to fire and external fire performance

Installations (safety hooks) covered by this document are reaction to fire Class A1 without the need for

1) 2)
testing and are deemed to satisfy external fire performance requirements .
8 Testing
8.1 Static load
8.1.1 Number of specimens

Each test shall be made once each on three different specimens. All specimens shall pass the tests.

8.1.2 Test in the hook base

The specimens (roof safety hooks) shall be fastened to the simulation of the load-bearing roof construction

according to the instructions of the manufacturer.

The test load of 1,5 kN shall be applied within one minute and maintained for a period of five minutes.

1) See Commission Decision 96/603/EC as amended by Commission Decision 2000/605/EC.

2) See Commission Decision 2000/553/EC.
---------------------- Page: 8 ----------------------
EN 517:2006 (E)

The deformation shall be measured under the test load of 1,5 kN and shall not deflect more than 5 mm in

direction of the force.

The test load is then increased to 1,5 kN x 1,7 kN = 2,6 kN for a further minute. In case of the maximum load

of 2,6 kN the functioning of the specimen and its fastening shall not be impaired.

NOTE The value of 1,7 is a safety factor.
8.1.3 Test at the anchorage point

Apply a static test load of F = 10 kN to the anchorage point for protective equipment against falls or for

restraint in the direction of use (direction of y-axis) for roof safety hooks.

Apply an additional static test load of F = 10 kN in the direction of the negative y-axis and in the direction of

the x-axis for roof safety hooks of Type B. The test loads in the y-direction and x-direction are applied to

different specimens.

Neither the roof safety hook nor the fastening shall become loose, and the test load shall be held safely.

8.2 Test of fatigue strength

Roof safety hooks shall additionally be tested in accordance with the requirements of 7.3.

Three test specimens shall be submitted to a drop test (see Figure 3).

The test specimens shall be fixed by their fastening systems to a simulation of the load-bearing roof

construction in a position between 70° and 90° from the horizontal.
The load and deflection criteria of the drop test shall conform to EN 364.

For the test, a hawser laid polyamide lanyard of three strands and of 12 mm diameter according to

EN ISO 1140 shall be used.
